1N3893A

Single Diodes Overview

The Microchip Technology 1N3893A is a standard fast recovery rectifier diode designed for high-power applications. It features a maximum DC reverse voltage (Vr) of 400 V and an average forward rectified current (Io) of 20 A. The device utilizes a DO-203AA (DO-4) stud-mount package, ensuring robust mechanical stability. Key electrical parameters include a maximum forward voltage (Vf) of 1.5 V at 38 A and a reverse leakage current of 10 µA at 400 V. The junction temperature range spans from -65°C to 175°C, with a typical reverse recovery time (trr) of 150 ns.

Single Diodes Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or certified suppliers. Confirm that the received part matches the specific 1N3893A designation and package type. Check manufacturing dates and lot codes against relevant quality standards. Ensure proper handling procedures are followed due to the stud-mount configuration. Review official datasheets for any recent product change notices affecting specifications or packaging.

Single Diodes Selection Notes

Select this component when a 400 V, 20 A fast recovery rectifier is required in a DO-203AA package. Consider the 150 ns reverse recovery time for high-frequency applications. Evaluate thermal management requirements based on the 1.5 V forward voltage at high currents. Ensure the operating junction temperature range meets system demands. Compare alternatives only if pin compatibility and electrical ratings align precisely.

Single Diodes Part Context

The 1N3893A belongs to the 1N3889–1N3893 series of fast recovery rectifiers manufactured by Microchip Technology. This series is engineered for general-purpose high-power rectification where speed and reliability are critical. The DO-203AA package provides a standardized footprint for industrial and commercial power electronics. Related variants may offer different voltage or current ratings within the same family.

Single Diodes Replacement Considerations

JAN1N3893A, JANTX1N3893A, and JANTXV1N3893A are parameter-equivalent alternatives available from Microchip Technology. These variants typically adhere to MIL-PRF-19500/304 qualification standards. Verify that substitute parts match the original electrical specifications and physical dimensions before integration.
